This cozy slow cooker fall harvest vegetable soup is the dish that turned me around on slow cooker vegetable soups. It’s not complicated—no fancy techniques, no obscure ingredients—but it delivers the kind of warmth that makes you want to curl up on the couch and ignore your phone for an hour.
For best results, cut vegetables uniformly (½-inch pieces). Do not overcrowd the slow cooker; it should be no more than two-thirds full. Resist lifting the lid during cooking. For deeper flavor, toast dried thyme and rosemary in a dry skillet for 30-60 seconds before adding. Season in layers: start with ½ teaspoon salt, adjust at the end. If soup tastes flat, add more salt or a second splash of apple cider vinegar. To thicken, mash some vegetables against the side of the slow cooker. To thin, stir in additional warm broth or water.
